I had both kids at the Heath, dd at birthing centre (beginning July 05, so one of the first births there!). Ds August 03, good because I had my community mw there but could easily have been shite, as soon as the next mw came on she started telling me I was about to kill my baby through incomepetance and clear inability to bf. (he managed 1 year, I think he was ok at it)
Think birthing centre is great but there are politics between the birthing centre and the hospital. I was admitted at one point to the hospital ward for pain relief and they planned on all sorts of, IMO, uneccesary intervention (breaking waters etc, they could f right off, totally uneccessary). Ended up threatening to discharge myself and go home, it was that bad. They eventually discharged me (I was literally on the verge of walking out, I only live 10 minutes away, so they could f off, basically) and the birthing centre admitted me.
Birthing centre itself was lovely, run by lovely mws, only one pool as far as I could see but lovely.
Just know your rights if you end up there, thats all! Especially as the birthing centre gives you near infinate toast and tea and you're lucky to get anything on the ward.
I do still feel just a little annoyed about my experience on the ward even now...
